له‌م فێركاریه‌دا هه‌وڵ ئه‌ده‌ین چۆنیه‌تی به‌كارهێنانی RecyclerView ڕوون بكه‌ینه‌وه كه‌ یه‌كێكه‌ له‌و View انه‌یی زۆر به‌كاردێت‌ بۆ پیشاندانی زانیاری به‌شێوه‌ی لیست له‌گه‌ڵ به‌كارهێنانی custom layout به‌ئاسانترین شێوه‌، هه‌روه‌ها فێرئه‌بین چۆن adapter بنوسین، وه‌ كۆنتڕۆڵی خانه‌كان بكه‌ین كه‌ كلیكی له‌سه‌ر ئه‌كرێت، له‌ كۆتایی‌ فێركاریه‌كه‌ وێنه‌یه‌كی وه‌ك ئه‌وه‌ی خواره‌وه دروست ده‌كه‌ین

با ده‌ست پێبكه‌ین:
سه‌ره‌تا Android studio بكه‌وه‌ و پرۆژه‌یه‌كی نوێ دروست بكه‌ به‌م شێوه‌یه‌ File ⇒ New Project دواتر به‌م شێوه‌یه‌ پڕی بكه‌وه‌

بۆ ئه‌وه‌ی بتوانین RecyclerView به‌كاربهێنین پێویسته‌ بچینه‌ به‌شی module یی پرۆژه‌كه‌ت و ئه‌م دوو dependency زیاد بكه‌ین
